WITNESSES v I INVENTOR EILAIRIE' J. FACKENTHALL, OF TRENTON, NEW JERSEY.

rIsHIne-smmsn.

To aZZ'w/wm it may concern Be it known that I, HART J. FACKEN- THALL,a'citizen of the United States, re-

siding at Trenton, in the county of Mercer and State of New Jersey, haveinvented certain newv and useful Improvements in Fishing-Sinkers; and Ido hereby declare the,

following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it ap pertains tomake and use the same.

It is the object of the present invention to provide a sinker fordeepsea fishing, and more particularly to provide asinker so shaped that itmay be cast a long distance and will carry the line withouttwisting andalso willv sink quickly through the water without being materiallydeflected from its original direction irrespective of the. roll of thesurf or the flow of the tide, and ultimately will anchor the line to theocean bottom without substantial danger of a change in positionirrespective of strong ocean currents. V r

The particular advantages of a sinker constructed" in accordance withthe present invention are hereinafter set forth in more detail,reference being bad to the accom-.

panying-drawings, in which Figure l is a perspective view of thecompletesinker; Fig. 2 is a top view of the same; Fig. 3 is a sideelevation, and Fig. 4 shows the sinker as viewed from its narrow orbottom end.

In the construction illustrated, the sinker is of metal and preferablyof heavy metal, such as lead or an alloy, and has embedded in it andpermanently attached, a' loop of wire, 1, to' which the fishing line maybe secured. The sinker is of conical shape, but wlth triangular cutsextending from base to apex, thereby forming five or a similar number offins or arms, 2, grouped sym metrically about the central solid portionor core of ,the sinker. Preferably, these fins are of substantial widthat their exposed edges, and .in cross section each is of triangularoutline, as clearly indicated by the figures of the drawing. 7 At theapex of the cone, all of the fins converge to a blunt point, 3, while attheir other ends these 'fins form a star shaped structure, asillustrated by Fig. 2. Preferably, the upper edges of each fin arebeveled off at 4:, thereby eliminating the sharp corner which otherwisewould exist at that point, and also havlng the efiect Specification ofLetters Patent.

of producing a relatively sharp corner 5 at the extreme outer part ofeach fin. These outer corners are very effective in preventmg the weightfrom rolling over a sandy bottom under the nfluence of a strongtide orsurf, for they are capable of digging into the sand and giving afirmanchorage to the line, and furthermore prevent free rolling of thesinker on the ocean bottom.

It has been found in practice that a sinker constructed as abovedescribed can be cast farther than a round sinker of equal weight, andwith less turning or twisting While in the air, and with less strain onthe line which is being thrown. The conical shape of the "sinker cutsdown the air resistance to its flight, and the projecting finssteady it"in flight and prevent it fnom whirling while traveling with the line.Also, the steadi- 'ness, given to its flightby the projecting fins,holdsthe sinker to its original direction and prevents the curving orswerving which might occur particularly in a strong wind if the sinkerwere not thus held against rapid whirling or spinning. I

When the sinker; strikes the water, 1ts. e

center of gravity is so positioned that it cuts through the waterquickly and reaches the bottom without being whirled by the surf orgreatly deflected by the t1de. It goes down quicker than a spherical 'we1ght, and is substantially free from the 'driftlng which characterizesthe descent of an ordinary sinker through rapidly moving water. When thesinker reaches the bottom, ,1t strikes on its apex and will either-embed1tself in the bottom or turn over on its side,

so that the projecting and relatively 'sharp' corners' 5*can dig intothe bottom and give anchorageto-the fishing line.

The sinker may be of any desired size and weight, and may vary fromtherelat1veproportions shown in the drawmg, as 1am. well aware.

I claim:

1. A fishingsinker of compact ing projecting fins radiatmg from a SO-lldcore in which the center-of gravity 1188, and a line anchorage in thecenter of the widest portion of the sinker .andnear the center ofgravity. W

form hav 2. A' fishing sinker, consistingsof a solid,

tapering central core, a pluralityof project-' ing fins radiatingtherefrom and converging until they meet at an apex, the center ofgravity lying in the central axls of the core the center of gravity ofthe sinker lying in said core and below the tops of said fins and a lineanchorage in said core opposite said apex and near said center ofravity.

4. A fishing sinker of conical shape consisting of a central core withmeans for attaching a line thereto,oand a plurality of finssymmetrically disposed about said core and converging at the apex of thecone, the

' center of gravity lying in the central axis of thecone and belowthetops' of said fins,

mama? said fins with said core forming a fiat star shaped base.

5. A fishing'sinker of conical and sym metrical outline having-a wireloop embedded therein to form a line anchorage at the base of the cone,said sinker being cut away from base to apex to form fins convergingat-the' apex of the cone, the other ends of said fins being beveledalong their sides and forming points to anchor the sinker to the oceanbottom. V In testimony whereof aflix my signature, in the presence oftwo wltnesses.
